Mosquito-frame

ABSTRACT

The invention pertains to a mosquito-frame, more specially to be used in metal frame structures, comprising a fly-wired frame realized in L-shaped or substantially L-shaped profile of which at least the flange directed outwards, is so very thin that it does not form a hindrance between the fixed and opening part of the window and on this frame, gadgets which permit the linking-up and the taking-out of the mosquito-frame out of the fixed frame structure.

As is well known, many mosquito-frames up to now, are made of wooden frames on to which a fly-wire is fixed. When the mosquito-frame is put in place, the opening part of the window cannot be shut, so that if the window must be closed, the mosquito-frame must come out.

This invention concerns a mosquito-frame that gives a systematic solution to all the troubles which accompanied up to now, the use of wooden mosquito-frames.

In this invention, the mosquito-frame, can be placed in a window frame or some other frame, so that the.

opening side of the window can be closed, without having to take out the mosquito-frame, consequently said mosquito-frame, although mobile, becomes a part .of the frame structure and permits the opening and closing of the window, without having to remove the mosquito-framef g The mosquito-frame presenting theaforesaid characteristics, consists principally of a fly-wired frame realized in L-shaped, Z-shaped or substantially L-shaped or Z-shaped profile, of which at least the flange, directed outwards, is so very thin that it does not, when the window is closed, from a hindrance between the fixed and the opening part of the window, and on this mosquitoframe, there are gadgets which permit the linking up of the mosquito frame with the fixed frame structure.

In order to make the characteristics of this invention more clear, there follows an example without any restrictions whatsoever, that has our preference, of a mosquito-frame according to the invention with reference to the accompanying drawings in which:

, FIG. 1 is a front view of a mosquito-frame according to the invention;

FIG. 2is a section following line Il-ll in FIG. 1;

FIG. 3 is a section following lineIlI-III in FIG. 1;

FIG. 4 is a section following line lVI\ in FIG. 3; FIG. 5 is a section following line V-V'in FIG. 1;

FIG. 6 is a partial view following arrow F6 in FIG. 5;

FlG.'7 is a view, seen from the outside, of a window frame where a mosquito-frame according to the invention has been placed;

FIG. 8 is a section following 7 and;

FIG. 9 is a section identical to that of FIG. 8, but where the opening part of the windowframe is shown open.

As shown in FIGS. l to 6, the mosquito-frame according to the invention, consists principally ofa frame 1 of which the measurements are taken with the greatest accuracy in regard to the measurements of the opened window-casement into which said mosquitoframe must be placed. The profile 2 that must be used for this frame 1, will be preferably made in Z profile. The outwardly extending flange 3 of the Z profile,

line vm-vm in FIG.

when the mosquito-frame is placed in the window-- frame in order to protect the .room in question, has such a'breadth that it cooperates withthe adjoining part of a fixed frame structure, against which the open going counterpart of the easement, in closed position,

normally abuts, whereas the inwardly extending flange 4 presents a breadth that is sufficient to permit the mosquito-frame in question to be fixed with the frame 1. The height of profile 2 as reflected by the height of the peripheral frame part 5, must be calculated in respect to the breadth of the so-called weather board, which is normally fixed to this folding window-casement to keep the rain out, in order to be able to shut the window while leaving the mosquito-frame in position.

The mosquito-wire 6, that preferably will be made of a synthetic material, is, in any suitable way, by glueing, stretching, riveting or otherwise, fixed with the inwardly extending flange 4. of frame 1, and, as illustrated, an ornamental profile 7 is attached to flange 4 over the edge portion of mosquito-wire 6. The ornamental profile 7 can have any form whatsoever and be fixed to the flange 4 by means of clamping-gadgets 8.

Preferably, in part 5 of the horizontal undermost profile 2, one or more holes 9- are made and covered by a small piece of mosquito-wire 10, these holes being necessary in view of draining away the water from the mosquito-frame by eventual rain.

Preferably, one .shall connect the vertical and horiontal profiles 2 of the mosquito-frame in a suitable 1 way by welding, riveting, screwing or such-like. To carry out this work, the extremities of profile 2 must be cut under an angle of 45 and fixed against each other by means ofa triangular small piece of plate 11 and rivets 12. I

In order to strengthen a mosquito-frame built in this way, it is advisable to add, for instance in the middle of the height of the'mosquito-frame, a profile 13, that among others can be made of an L-profile whereof the horizontal flange is directed inwards, so that this profile can be used as a grip for placing or respectively taking out the mosquito-frame, when for instance this is necessary for cleaning purposes. 7

In order to keep this mosquito-frame firmly pressed against the fixed part of the window-easement, when the window is open, one should fit, on the two sides, preferably the vertical ones, gadgets that keep the mosquito-frame, after placing in the fixed part of the window-casement, firmly attached. For that purpose, one can use small sliding bolts, swivel bolts, or balls under spring-pressure. Y

These gadgets, as shown in the drawings, are simple rollers 14, made of hard rubber, that can be'horizontally pushed in and that under spring-pressure, come automatically. These gadgets with rollers or balls, are well known and can be obtained in the market.

The roller 14 of each gadget or bolt, passes through a suitable hole 15 in the relative part 5 of the profile 2.

It is quite evident that at least outwardly extending flange 3 of profiles 2, must be made as thin as possible, for instance to the order of 0.5 to 1.5 mm, so that after placing the mosquito-frame in question in the fixed part of the window-casement, the opening part of the window or such-like, can still be closed without having to take out the mosquito-frame.

This is more specially possible for metal and still more specially so for aluminium window frames, because in between-the fixed window structure 16 and the opening part of the window 17, there is left a space or opening that normally is sealed up by a rubber band or such-like l8.

It is this space that is used, according to the invention, to place the flange 3 of the mosquito-frame as shown in FIGS. 8 and 9, while keeping the possibility of closing the opening part of the window As shown in FIG. 8, one obtains that the opening part of the window can be closed without the mosquitoframe being in the way, and, when the opening part of the window is open, see FIG. 9, the rollers 14 hold the mosquito-frame firmly secured in the fixed window frame structure.

Thus is realized a very simple mosquito-frame, that can be placed and stay in position, independantly of the open or closed state of the window.

It is clear, that the above-mentioned Z-shaped profile can be replaced in any appropriate way, by another profile, on condition however that above-mentioned flange 3 is respected and that the profile has sufficient height. In this way, the Z-shaped profile can, for instance, be efficiently replaced by an L-profile or suchlike, whereby the fly-wire can for instance, be attached by an adhesive strip against the exterior or interior side of the body of this L-profile or such-like] The present invention is evidently not limited to the example described and illustrated bythe accompanying drawings, but such a mosquito-frame can be realized in all shapes and dimensions ,without exceeding the bounds of this invention.
